Specification of Letters Patent.

Application filed October 14 1910. Serial No, 586,991.

To all whom, it may concern:

Be it known that I, HENRY Hnss, a citizen of the United States, residingat- Philadelphia, in the county of Philadelphia. and State ofPennsylvania, have invented certain new and useful Improvements inMachines for Formin Grooves and the Like Upon the Sides of Rollers, &c.,of which the following is a specification, reference being had thereinto the accompanying drawing. ly invention relates to machines forforming grooves and the like upon the sides of rollers and otherobjects, and is more particularly disclosed herein in connection withthe formation of conicallyi shaped or angularly located grooves upon therollers used in journal bearings, such grooves being intended to formabutting surfaces, whereby the end thrust on the rollers is resisted ortransmitted and also the rollers are held in normal position in relationto the other parts of the bearing. It will be obvious, however, that themachine is capable of broader application and in fact may be employed toproduce grooves of. various forms and location upon any desired object.

Referring to the form of rollers previ ously mentioned, it will be seenthat in order to obtain the greatest accuracy and uniformity, and theleast resistance and wear,

it is essential that the oonically shaped T conically 'cally shaped asto their general outline,

grooves shall be absolutely true and similar and that the position ofthe grooves, that is to say, their distance the rollers, shall beexactly the same in all. These results I secure by forming the groovesby the machine now to be described. I

In the accompanying drawing I have shown my invention in preferred form,and as particularly applied to the production of shaped or angularlylocated grooves upon the surfaces of rollers, cognut obviously sucharrangement is simply by way of example and for the purpose ofillustrating one form of myinvention, and

many changes and variations may be made therein without departing fromits spirit. Generally speaking, I desire it to be expressly understoodthat I do not limit myself to any specific form or embodiment exfrom theends of,

l a stop D ceptin so far as such limitations are specitied n the claims.

Referring to the drawing: Figure 1 is an Patented pr. 16, 1912.

elevation, partly in section, of the essential port-ions of a machineembodying my invention, and Fig. 2 1s a transverse sectional Viewthereof, taken substantially on the 5,

line 2-2 in Fig. 1.

As illustrated in the drawing, the rollers A A are con-ically shaped asto their general outline and it is desired to form grooves or cuts a-aupon the sides thereof, such grooves orcuts constituting in effectconical abutting surfaces for the purposes previously specified. Thegeneral conical formation of the rollers A A is however not essential tothe employment of my machine, which is designed generally for theproduction of grooves upon any objects where they may be desired. Therollers A A are mount-ed in series between a ring C and an internalrotatable disk B, the ring and disk being suitably shaped to correspondto the form of the rollers A A, and by disposing the rollers in themanner indicated, they are brought into proper angular position to besubjected to the action of thegrinding tool D.

The tool D may be rotated in any desired manner, such for instance asthe spindle D gearing'D countensha-ft D and gearing D actuated from thepower driven shaft D The tool -D is splined upon the spindle D so as tobe capable also of longitudinal movement thereon, which movement iscontrolled by a handle D and is limited by In this manner the grindingaction of the tool upon the rollers A. A may extent.

The disk suitable connections whereby it' may be rotated, comprising 'ashaftB and geziring B connected to the power driven shaft D Because ofthe contact of the disk B with the rollers A A, the latter are caused to1'0- tate individually, so as to present successively and continuouslytheir sides to the action of the cutting edge of the tool D wherea-a areformed. As shown:

ed in the machine in substantially the a'n-V 'be governed and regulatedto any desired B is shown as provided with 1 gular' relation to eachother that they ocers need not be arranged in the exact anfilipy inthejournal bearing, and it will be seen that by the employment ofthe'machine, absolute un formity is secured as to the position of thegroovesin the sides of therollers, and also the exact similarity of thegrooves formed therein. It will be obvious that my-improved machine maybe employed in many different "ways without'departing from the spirit ofmy invention. Thus, for instance, the roll gular relation previouslydescribed, all that is essential in this respect being that the angularrelation adopted should be the one Calculated to give the desired pitchand position to the grooves. As previously pointedout, also, the mainportion of the object operated upon need not beconical, as in theparticular illustration given. Again, the internal disk B might remainstationary,

and the external ring 0 be rotated to profluce the same result, namely,'the indix-y' idual rotation of the rollers or otherwork.

"andI regard them all as comprised Within Or again, both the externalring and the internal disk may be rotated, or other and entirelydifi'erent means may be employed to secure'the rotation of the work.Similarly,- the particular means employed for forming the-grooves maybeentirely different from that herein disclosed, and suchmeans mightebnsist-of milling tools, wood working tools, etjt, dependent upon thematerial employed andthe nature of the result required. Not onlymay,.the p,osition and, angular relations of the groovesmpon the sidesof the rollers.

be varied to suit the particular needs, but in addition thereto, their Iconformation and shape may be altered at will, as for instance bychanging the shape, character-and location of the cutting orgrindinginstruments. Aga n, the'form of the tool may be variedas;j:desired in accordance with the character of the/work, to beperformed, thereby; and "similarly itslocation may be changed, as Theseand many other variations Wlll. sugwell as its point of application tothe work.
